The LVAD is the most common device applied to a defective heart (it is sufficient in most cases; the right side of the heart is then often able to make use of the heavily increased blood flow), but when the pulmonary arterial resistance is high, then an (additional) right ventricular assist device (RVAD) might be necessary to resolve the ...
The EF of the right heart, or right ventricular ejection fraction (RVEF), is a measure of the efficiency of pumping into the pulmonary circulation. A heart which cannot pump sufficient blood to meet the body's requirements (i.e., heart failure) will often, but not invariably, have a reduced ventricular ejection fraction.
Pump thrombosis is defined as a specific case of a major device malfunction. In turn, device malfunction is as defined by Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) as a failure of one or more of the components of the mechanical circulatory support systems which either directly causes or could potentially induce a state of inadequate circulatory support (low ...
A blood volume increase would cause a shift along the line to the right, which increases left ventricular end diastolic volume (x axis), and therefore also increases stroke volume (y axis). The Frank–Starling law of the heart (also known as Starling's law and the Frank–Starling mechanism ) represents the relationship between stroke volume ...
Major factors influencing cardiac output – heart rate and stroke volume, both of which are variable. [1]In cardiac physiology, cardiac output (CO), also known as heart output and often denoted by the symbols , ˙, or ˙, [2] is the volumetric flow rate of the heart's pumping output: that is, the volume of blood being pumped by a single ventricle of the heart, per unit time (usually measured ...
Left ventricular hypertrophy with secondary repolarization abnormalities as seen on ECG Histopathology of (a) normal myocardium and (b) myocardial hypertrophy. Scale bar indicates 50 μm. Gross pathology of left ventricular hypertrophy. Left ventricle is at right in image, serially sectioned from apex to near base.

test cardiac function in the right, or left ventricle. Cardiac ventriculography is a medical imaging test used to determine a person's heart function in the right, or left ventricle . [ 1 ] Cardiac ventriculography involves injecting contrast media into the heart's ventricle(s) to measure the volume of blood pumped.
